Neptune with Dark Spot (Blue Light)

About the colours

This image is a single, monochrome filter that isolated blue light (F467M) was used to record overall brightness. These brightness values were translated into a range of bluish hues. Such color "maps" can be useful in helping to distinguish subtly varying brightness in an image. Blue: F467M
